To all 'tolto/m, t may camera it known that I, Daunen Burnin, acitizeuof the United States, and resident. ol

Newport. in the county of Newport and State oi. Rhode Island, haveinvented certain new and useit'ul lrnprtnf'einents iu Safety* Razors, ofwhich the following is a specifica.- t-ion.

This invention relates to safety razors, the preferred embodimentthereof beituil illustrated by the accompanying drawings.

Figure l' represents a side elevation of the razor in one o't' itsoperative positions. Fig. 2 represents an elevation o't the oppositeside oit' the razor in the same position. Fig. Il represents aperspective View of the blade, the lower end of the shank being brokenaway.i Fig. 4 represents the satety guard, the guard portion thereofbeing shown in longitudinal section and the shank thereof being shown inelevation. Fig. 5 represents a longitudinal section, on a larger scale,ot' interlocking portions of the blade and guard, the interlockingportions ot the blade shank and guard shank being shown in elevation,and the intermediate portions being broken away. (See line 5-5 of Fig.l.) Fig. 6 represents a View similar to Fig. 5, showing the blade andguard adjusted to a dill'erent position whereby a. greater space is leftbetween the blade and guard. Fig'. T repre sentis a cross section in theplane indicated by line 7-7 of F ig. 2, showing the blade and guard inthe relation corresponding to the adjustment shown by Fig. Fig. Srepresents a cross section similar to Fig. 7 but showing the blade andguard in the relation corresponding to the adjustment shown by Fig. 6.Fig. 9 represents a cross section in the plane indicated by line 9---9ot' Fig. 2.

The same. reference characters indicate the same parts wherever theyoccur.

The blade comprises a longitudinal central body portion l() and twooppositely dis posed cutting edges l1, 1l. The blade provided with ashank 12 whereby' the blade may be attached to a handle 13. As shown byFigs. l and 2 the shank and handle are connected by a pivot; llt in suchmanner that the yblade may swing into and out of the handle as in thecase of an ordinary single-- edge razor. l/Vhen the blade is without. aguard it maybe honed and stropped in the usual manner, as in the case ofthe ordinary old-fashioned razor, the body portion ltllben ing`relatively thick'. as shown by Figs. 7 and 8, to engage the hone orstrop to determine the desired bevel or angle given to the cutting edgesand also to stillen the blade.

'the blade has` suitable provisions whereby a guard may be attached. itsshown by lt`ig. il. the guard comprises a longitudinal central bodyportion l5, guard fingers or projections ,16, and a shank 1T. Thelingers or projections 1G are disposed in two series oppositely disposedso as to cooperate respectively with the two cutting edges oli the bladein the well-known manner. The toe ot the blade is provided with a notchA1S (see Figs. il and :tor the receptit'in ot a'hook lfl of the guard.The hook is inserted in the notch by inoring the guard Ytrom the toetoward the heelo't" the blade. lhe inner surface 2t) ol the hook isinclined. and the cooperative surface Ql o li the blade is likewiseinclined so that the, confronting surfaces of the -guard and blade willbe. drawn toward each other as the guard is moved toward the heel ot theblade. ,l'he shank ol.E the guard is provided with ahead which comprisesears 9*? and a neck or web Qhthe ears extent'ling;` laterally inopposite directions :trom the neck, and the neck connecting the earswith the shank.

The shank ot' the blade is provided with a keyhole. slot for thereception of the head ot the guard. The enlarged portion 2t ol` thiskeyhole slot is large enough to enable the head to passthrough. afterwhich the neck Q3 oit the guard is adapted to traverse the narrowelongatetl portion ot the keyhole slot. The blade shank l is providedwith notches QG adapted to receive the ears QQ, said notches beingdisposed between the ends ot the eltlngated portion of the keyhole slot.

The (poration ol assembling the guard and blade is as `follows:M'lhehead at the lower end ol the guard shank is first passed through theportion 2lY o't` the keyhole slot. 'lhe guard is then 'tree to slidetoward the. pivot tt, and when so moved the neck 25? enters theelongated portion Q5 of the slot.

During this Inoveinent the point. of the hook itt) at the outer end otthe guard is inserted in the notch i" the blade. 'When the ears ol theguard head register with the notches 20 in the blade shank, the earssnap into these notches`as shown by Fig. 5 and" the guardand blade arethus completely assembled, the confronting 'faces `olf the guard andblfade being drawn together durl angle to each other. This bend ispreferably located at the junction of the shank and body portion. lVhenthe head of the guard is ullyinserted into the enlargement of thekeyhole slot, the shank 17 lies in contact with the Hat surface of theblade shank 12. and the bend 27 causes the body portion of the guard todiverge with relation to the body portion of the blade. lt is thereforenecessary to spring the free end ot the guard toward the blade in orderto insert the hook 19 into the notch 18. When the guard is so Sprung,its body portion becomes curved, as indicated by ldotted line 15. Thenormal angular relation of the body portion 15 and shank 17 causes theears 22 to spring/into the notches 26 and also causes t-he body portionof the guard to stand away from the body portion of the blade as shownby Fig. 7, thus leaving a clear space 28 between the two body portions.This space 28 is desirable because it enables the lather to passthrough, so that the lather will not all col lect upon the operativeedge ot the blade. Thisfspace also facilitates the removal of thelather, because water may be freely cir culated between the blade andguard either by immersion or by holding the razor under a runningstream.,

The guard is adjustable toward and from the cutting edges and itsadjustment is etfected by relative longitudinal movement of the bladeand guard. For example, Figs. 1,2 and 5 show the guard in such positionthat the ears 22 occupy the notches 26, and show the hook 19 insertedinto the notch 18 as far as it will go. In this position the space 28between the guard and blade is rel-l atively narrow. lf it be desired,to increase the space 28 as shown by Fig. 8, so as to shave moreclosely, the desired adjustment is obtained by springing the guard shank17 so as to remove the ears 22 from the notches 2G and by then movingthe guard slightly toward the toe of the blade, provided it is not movedso far as to entirely withdraw the hook 19 from the notch 18.

Fig. G shows an intermediate adjustment ot the guard. As the guard ismoved toward the toe of the blade, the body portion l15 vsjningslaterally away from the blade as far as the inclined surfaces 20 and 21will permit, and it is duc to the inclination of these surfaces and tothe longitudinal relative movement of the guard yand blade that thespace 28 between the guard and blade ing and adjusting the guard, and asthe h and is at such time at a safe distance troni.

the cutting edges, and as the reaction upon the hand tends to move thehand away from the cutting edges., there is no possibility o the handcoming. in contact with thecutt'ing edges. rlhe friction of the shank 17upon the shank 12, due to the springiness of the guard, is suiiicient tohold the guard at any desired intermediate position. The handle '1.3 issimilar to the handle of an ordinary old-fashioned razor, having twoside pieces, as shown by Fig. 2, suitably spaced toreceive between themthe blade and attached guard.

It is obvious that the blade may be turned to'any desired anglerelatively to the handle and that the razor may be used in exactly thesame way as an ordinary old-fashioned.

razor, but that in addition to such use it is.

capable of cutting -in opposite directions, provided the blade is rockedupon its body portion when the direction of cutting movement isreversed. Such rocking of the blade does not necessitate any otherchange in the may be varied. The unlocking of the Shanks position of therazor relatively to the hand. u

I claim:

1. A. safety razor comprising a blade and a springy guard thereforhaving integral interengaging connecting portions at one end andcontacting portions at the opposite end, and extensions beyond saidcontacting portions, said ex'tensions having integral interengagingconnecting` portions whereby said contacting portions are brought tobear against each other and whereby the guard, between said contactingportions and the first mentioned connecting portions, is sprung awayfrom the blade. i

2. A safety razor comprising a blade and a guard adjustablelongitudinally of the cutting edge, said blade and guard havingcooperative portions whereby their confronting ksuri'aces are variablyspaced one from the other in consequence of adjusting the guard asaforesaid.

3. il. safety razor comprising a blade and a guard having anunobstructed spaceebetween them for the passage of lather, and ha vine'cooperative connecting portions adapted to slide relatively upon eachother, one of said parts having an inclined surface engaging the otherof said parts for variably spacing said parts one from the other whenmoved relatively as aforesaid.

4. A safety razor comprising a blade and a guard each having a shank,said blade shank having a keyhole slot and said guard shank having afianged head adapted to `slide on the blade shank in interlockedrelation with said slot.

5. A safety razor comprising a blade and a springy guard, said membershaving cooperative-portions for connecting the blade andguard and beingcapable of relative longitudinal movement, said portions havingcooperative surfaces which are held in Contact by the springiness ofsaid guard, one of said surfaces being inclined to enable the guard tospring away from the blade in consequence of relativelongitudinalmoveinent of the blade and guard.

6. A safety razor comprising a blade and a guard each having a shank,said Shanks having coperative interlocking portions, the toe of theblade and guard also having cooperative portions for holding the bladeand guard connected, the guard being bonrrly longitudinally so that itis spaced apart lroni the blade to provide a pass: jeway 'for latherbetween the blade and guard.

7. A safety razor comprising a blade and a guard each having a. shank,said Shanks having cooperative interlocking portions, the toe o1 theblade and guard having cooperative portions for holding the blade andguard connected, the guard being bowed longitudinally so that it isspaced apart 'from the blade to provide a passagewajr ior lather betweenthe blade and guard, the cooperative connecting portions of the bladeand guard4 having provisions for varying the distance between theinter1nediate portions of the blade and guard.
